Vancouver-based pH7 Technologies has developed a unique electrochemical processing method for combing through mine tailings to recover metals critical to the global energy transition.
Take the yawning gap between copper supply and skyrocketing demand in the age of artificial intelligence, which could lead to an annual shortfall of 10 million tonnes by 2040, according to a recent report from S&P Global Energy. That’s almost twice the annual output of Chile, the world’s biggest copper-producing country.
To fill the gap, the industry would need to get approvals and build the equivalent of the world’s 20 biggest existing mines.
However, Mohammad Doostmohammadi says, there’s an estimated 20 million tonnes of copper sitting in the spent tailings of North American mines.
